This has a cost but nothing close to what you’d have to pay investors in a pool, which is something else you mentioned.

It is actually just a tool to create the already mentioned accelerated depreciation.

I'm currently biased towards Indianapolis based on its job growth and affordability, but you could honestly find deals in any of the markets you mentioned (and if your heart is set on the Atlanta metro area, I'd strongly suggest the towns Union City and Fairburn based on their growth, appreciation, and price -- I almost closed on a good BRRRR deal in Fairburn but the rehab was just out of my budget). 

As Account Closed mentioned, the first question is to decide if you want to invest actively or passively. 

I advertise the houses that way, even if there's an appliance or two that the previous owner has left in them and I don't mention them so that the people coming aren't (or shouldn't be) expecting to find them. 

I built my first modern 7 years ago and like you agree that some (not all) moderns will age out.

These are probably dummy accounts.4) If you look at Robert Kiyosaki's wikipedia (Criticism & controversy section), it mentions a similar company to Legacy.

If we are talking rental properties, then I completely agree with B, C, and D that he mentions.

You could have it show up under 3 bedrooms when guests are looking for that, but you should mention in your description that it is 2 bedrooms + a loft. 

We plan to rebuild, but our neighbors are aging and do not wish to go through a rebuild.
